I've got a fix ready for everything listed. Should have an update out soon.
The enemies not showing up in the Bestiary are being recorded, but for some reason the Bestiary's "highest enemy ID discovered" counter was stopping early. I'll figure out why this is happening, but until then, the next fix will just let you scroll all the way down to the very last undiscovered enemy. (Page Up and Page Down can also scroll through the menu faster.)
I'm glad you like the flavor text for the Blackboard! As for the Black Knight- that text is a relic from an earlier plan, where the Black Knight would show up there and help you fight a completely different monster.
